Baron begins her analysis by situating instant messaging as a form of computer-mediated communication and attempting to create a profile for IM communications among undergraduate students. She first reviews the linguistic differences in spoken speech: social vs. informative speech and standard vs. non or sub-standard usage by men and women. In terms of written language, she reviews concepts related to personal letter writing and studies about gender identification of online texts. She analyzed the IM data for turn taking, sequences, conversation length, and lexical issues to determine possible effects of gender. She found no differences in turn taking, but found that women had greater overall conversation length and length of ending sequences. From the lexical analysis, Baron found that men used more contracted forms of words (e.g. "I'm" instead of "I am") than women. Most interesting to me, and not at all surprising given my real-world online experiences, was the finding that women used more emoticons than men in the IM conversations.
